The Rear Wing Inner and Moulding are crucial elements of a Peugeot vehicle's body structure, significantly contributing to its overall aesthetics, aerodynamics, and structural integrity. On this page, you will find a detailed diagram showcasing the various components that constitute the rear wing inner and moulding assembly. This comprehensive guide will cover the technical purpose of these parts, their connection with other vehicle nodes, repair, installation, or replacement procedures, as well as the technical characteristics of the parts included in the assembly.

Technical Purpose of the Rear Wing Inner and Moulding

The rear wing inner and moulding have two primary roles: reinforcing the vehicle's structural integrity and enhancing its aerodynamic performance.

Structural Integrity: The rear wing inner panel acts as a support structure, providing rigidity to the rear quarter of the vehicle. This reinforcement is crucial for maintaining the vehicle's shape and resisting impacts, ensuring the safety of passengers in the event of a collision.
Aerodynamic Performance: The outer moulding of the rear wing improves the vehicle's aerodynamic profile. It helps in reducing drag, which in turn contributes to fuel efficiency and a smoother ride. The moulding also adds to the aesthetic appeal, giving the vehicle a more refined look.

Connection with Other Nodes

The rear wing inner and moulding are connected to several other essential components within the vehicle's body structure. These connections ensure that the vehicle operates as a cohesive unit. Here’s how it integrates with various nodes:

Rear Panel: The rear wing inner attaches to the rear panel, providing additional support and rigidity to the vehicle's rear structure.
Rear Wheel Arch: The rear wing inner and moulding envelop the rear wheel arch, protecting it from dirt and debris while contributing to the vehicle’s aerodynamic design.
Trunk Floor: The inner panel connects to the trunk floor, offering stability and reinforcing the rear portion of the vehicle's body.
Side Sill: The rear wing inner panel extends toward the side sill, ensuring that the structural load is evenly distributed across the vehicle chassis.

Parts Included in the Assembly

The complete assembly of the rear wing inner and moulding includes multiple components, each with a specific role. These components complement each other to provide both structural strength and visual appeal:

Rear Wing Inner Panel: This is the primary structural component made from high-grade steel or aluminium. It's designed to withstand impacts and provide rigidity.
Outer Moulding: Made from durable plastic or fiberglass, this component covers the outer surface of the rear wing inner, enhancing the overall design and aerodynamic efficiency.
Mounting Brackets: These metal or plastic brackets are used to secure the rear wing inner and moulding to the vehicle's main body.
Weather Strips and Seals: These components are made from rubber or silicone and help in waterproofing the area around the rear wing, preventing moisture and dust ingress.
Fasteners: screws, bolts, and clips used to hold all the components together securely.

Technical Characteristics of the Parts

Below are the technical characteristics of the individual components in the rear wing inner and moulding assembly:

Material Strength: The rear wing inner panel is generally made from high-strength steel or aluminium to endure high impact, while the outer moulding is often constructed of ABS plastic or fiberglass for lightweight durability.
Corrosion Resistance: Materials like galvanized steel, coated aluminium, and treated plastics are used to resist corrosion, especially due to exposure to elements like road salt, water, and UV rays.
Aerodynamic Efficiency: The design of the outer moulding is streamlined to minimize air resistance and improve fuel efficiency.
Impact Resistance: The inner panel is designed to absorb and distribute impact forces efficiently, safeguarding the vehicle's structural integrity.
Lightweight Construction: Modern materials and manufacturing processes ensure that these components are both strong and lightweight, contributing to better vehicle handling and fuel efficiency.

Repair, Installation, or Replacement of the Rear Wing Inner and Moulding

Repair or replacement of these components may become necessary due to physical damage or wear over time. Here are the essential steps and considerations for the same:

Indications for Repair or Replacement

Dents and Dings: Visible damage to the outer moulding or rear wing inner panel can compromise both aesthetics and structural integrity.
Corrosion: Rust or corrosion on the inner panel or mounting brackets can weaken the structure, necessitating replacement.
Misalignment: Gaps or misalignment between the rear wing and adjacent panels can affect aerodynamic performance and require adjustment or parts replacement.

Steps for Installation or Replacement

Preparation: Before starting, make sure you have the correct replacement parts and necessary tools, which may include screwdrivers, wrenches, and alignment tools.
Vehicle Setup: Lift the vehicle safely using jacks and ensure it is stable. Remove any components obstructing access to the rear wing inner and moulding.
Remove Damaged Parts: Carefully unscrew and detach the damaged or worn rear wing inner and/or moulding. Note the positioning and connections for accurate replacement.
Check for Corrosion or Damage: Before installing the new parts, inspect the connecting areas for rust or structural damage. Repair or treat these areas as needed.
Install New Parts: Align the new rear wing inner panel and secure it using the mounting brackets and fasteners. Ensure it fits snugly and securely. Attach the outer moulding, ensuring precise alignment to maintain the vehicle's aerodynamic efficiency.
Reassemble Components: Reattach any removed components, such as wheel arch liners or trim pieces, ensuring all connections are secure.
Final Check: Verify the alignment and secure fit of the new parts by inspecting the gaps and alignment with adjacent panels. Conduct a road test to ensure there are no unusual sounds or issues.

Following these steps will ensure that your Peugeot's rear wing inner and moulding are correctly installed or replaced, maintaining both the structural integrity and visual appeal of the vehicle. Regular inspection and timely maintenance of these components can enhance the longevity and performance of your Peugeot.
